  • FIG. 1 is an exploded perspective view of a wheel mechanism according to an embodiment of the present invention
  • FIG. 2 is a sectional view of a wheel assembly according to a first embodiment of the present invention, incorporating the wheel mechanism of FIG. 1 ;
  • FIG. 3 is a sectional view of a wheel assembly according to a second embodiment of the present invention, incorporating two wheel mechanisms of FIG. 1 ;
  • FIG. 4 is a sectional view of the wheel assembly of FIG. 2 , when loaded.
  • FIG. 1 An exploded perspective view of a wheel mechanism according to an embodiment of the present invention is shown in FIG. 1 , and generally designated as 10 .
  • the wheel mechanism 10 includes a circular outer wheel 12 , which includes an outer ring 14 fixedly joined with a central circular disc 16 .
  • the outer wheel 12 is made of hard rubber double-injected to and thus joined with the central circular disc 16 (which is made of acrylonitrile butadiene styrene (ABS)), having a central circular hole 18 .
  • the outer ring 14 is thus made of hard rubber.
  • Two circular recesses 20 are formed on either side of the central circular disc 16 .
  • On each of two major surfaces 22 of the central circular disc 16 are formed a number of concentric grooves or at least one spiraling groove.
  • the thickness of the rubber damper 24 is the same as the depth of the recess 20 of the outer wheel 12 , such that the rubber damper 24 is fully received within the recess 20 of the outer wheel 12 .
  • Each of the rubber dampers 24 has a central circular hole 30 which is of the same diameter as the central circular hole 18 of the central circular disc 16 of the outer wheel 12 .
  • each rubber damper 24 and on an opposite side to the outer wheel 12 is a respective circular slider washer 32 , which is made of plastic (e.g. acrylonitrile butadiene styrene (ABS) or polyurethane) or a metal (e.g. copper or steel).
  • the outer diameter of the slider washer 32 is the same as the inner diameter of the circular recess 28 of the rubber damper 24 , so that the slider washer 32 is fully received within a respective recess of the circular recesses 28 of the rubber damper 24 .
  • Each of the slider washers 32 has a central circular hole 34 which is of the same diameter as the central circular hole 18 of the outer wheel 12 .
  • a circular inner wheel 36 which is made of a plastic (e.g. acrylonitrile butadiene styrene (ABS)) or a metal (e.g., aluminum) or a metal alloy (e.g., a magnesium alloy).
  • ABS acrylonitrile butadiene styrene
  • the inner wheel 36 has a generally planar circular disc 38 and a hollow cylindrical member 40 which extends away from the disc 38 towards the outer wheel 12 .
  • the outer diameter of the cylindrical members 40 is smaller than the diameter of the central holes 34 of the slider washers 32 , that of the central holes 30 of the rubber dampers 24 and that of the central circular hole 18 of the outer wheel 12 , such that when assembled, the hollow cylindrical members 40 of the inner wheel 36 extend through the central holes 34 of the slider washers 32 , the central holes 30 of the rubber dampers 24 and the central circular hole 18 of the outer wheel 12 .
  • the outer diameter of the inner wheel 36 is the same as the inner diameter of the circular recess 28 of the rubber damper 24 , so that the slider washer 32 is received within a respective recess of the circular recesses 28 of the rubber damper 24 .
  • each planar disc 38 of each respective inner wheel 36 is co-planar with an annular longitudinal surface 31 of a respective rubber damper 24 , which is also co-planar with an annular longitudinal surface 19 of a respective outer wheel 12 ;
  • the inner diameter of the hollow cylindrical members 40 is the same as or slightly larger than the outer diameter of an axle 44 , so that, when duly assembled, the axle 44 is received within the two hollow cylindrical members 40 which abut and are aligned with each other in an end-to-end manner.
  • FIG. 2 shows a wheel assembly, generally designated as 100 , in which the assembled wheel mechanism 10 is engaged with an attachment member 46 via the axle 44 , in which the wheel mechanism 10 may rotate relative to the attachment member 46 about the longitudinal axis L-L of the axle 44 .
  • the attachment member 46 may be attached to or be integral with another object, such as a luggage trolley, delivery trolley, furniture item or hospital bed. The installation of the wheel assembly 100 with the wheel mechanism 10 facilitates movement of the object.
  • the wheel mechanism 10 is symmetrical about an axis A-A which bisects the outer wheel 12 and is perpendicular to the longitudinal axis of the wheel mechanism 10 , which coincides with the longitudinal axis L-L of the axle 44 when the axle 44 is received within the wheel mechanism 10 .
  • FIG. 3 shows a second embodiment of a wheel assembly, generally designated as 200 , in which two wheel mechanisms 10 are engaged with an attachment member 146 via a single axle 144 , such that the wheel mechanisms 10 may rotate relative to the attachment member 146 about the longitudinal axis M-M of the axle 144 .
  • the attachment member 146 may be attached to or be integral with another object, such as a luggage trolley, delivery trolley, furniture item or hospital bed.
  • On the outer longitudinal side of each wheel mechanism 10 is an end plate 148 , and on the inner longitudinal side of each wheel mechanism 10 is a gap washer 150 which separates the respective wheel mechanism 10 and the attachment member 146 .
  • FIG. 4 such shows the configuration of the wheel mechanism 10 when it is loaded, i.e. when a significant force exerts radially on the rubber damper 24 .
  • the wheel mechanism 10 when the wheel mechanism 10 is engaged indirectly to another object, e.g. a luggage trolley, via the axle 44 , the object will bear on the axle 44 , which will in turn exert a vertically downward force (indicated by the arrow F in FIG. 4 ) via the inner wheels 36 to the rubber dampers 24 and the outer wheel 12 .
  • the lower parts i.e.
  • the parts closer to the ground G) of the rubber dampers 24 will be compressed, thus allowing the inner wheels 36 to descend relative to the slider washers 32 , and consequently bringing about two gaps 60 between the rubber dampers 24 and the inner wheels 36 .
  • the creation of the gaps 60 is also made possible because of the difference between, on the one hand, the outer diameter of the cylindrical members 40 of the inner wheel 36 and, on the other hand, the diameter of the central holes 34 of the slider washers 32 , that of the central holes 30 of the rubber dampers 24 and that of the central circular hole 18 of the outer wheel 12 .
  • the wheel mechanism 10 produces significantly less noise during operation.
  • the rubber dampers 24 separate the inner wheels 36 from the outer wheel 12 , transmission of vibration shock from the ground through the outer wheel 12 to the inner wheels 36 during rotation of the wheel mechanism 10 on the ground is reduced.
  • the concentric grooves or at least one spiraling groove on the two opposite major surfaces 22 of the central circular disc 16 of the outer wheel 12 also assist in reducing transmission of vibration shock from the ground through the outer wheel 12 to the inner wheels 36 during rotation of the wheel mechanism 10 on the ground.
